Thule FreeRide 530 meets all requirements for a very good bike rack: - It can be assembled fairly easily - It can be easily mounted on the roof rack (which must, of course, already exist) - Installation on the roof crossmember with a square profile is easily - The delivery was very punctual and completely - At the first ride over 1000 km, you have two side by side mounted bicycles and the bicycles were not noticed by the clamping lock principle extremely tight until the arrival - Only the metal support bracket, with which the carrier is attached to the roof crossbars, fall in assembly quite fast through the mounting slots, which may annoy some All in all, an excellent bike rack at a fair price, I think.
